XTCE13 — Spelling error for Arguments in XTCE 1.2 proposed

Reported by Michel Sibon of Thales. There is a spelling error of the word "Agument" in RelativeTimeArgumentType in XTCE 1.2 proposed. It has been present for some time because it is also reflected in the xtcetools schema file that was based on an early XTCE 1.2 releae schema.

<element name="RelativeTimeAgumentType" type="xtce:RelativeTimeArgumentType">

<documentation xml:lang="en">Describe an argument type that has an engineering/calibrated value in the form of a duration in time.</documentation>
</annotation>
</element>
